I am performing live audio streaming from a server to a client using gstreamer.
Server is set up as RTSP server ,and client will be using VLC to receive the input stream.
Server program is sends the sound card audio to the client, . but unfortunately vlc at the client side is showing the following error
YOUR INPUT CAN'T BE OPENED
VLC IS UNABLE TO OPEN THE PROBLEM 'RTSP://LOCALHOST:8554/SER'CHECK THE LOG FOR DETAILS
Can anyone explain to me what the problem is? Is it something related to VLC version? I think the server is OK because it is showing messages telling it started the listening process. Please suggest me the methods to correct this error.
When this happens you can change the RTSP to RTMP or MMS and it should work unless the link is dead

I have been exploring on how to live stream from iPhone. I will have to publish a stream at URL to Wowza server that I came to know. Other thing is that I will require a library for iOS to encode and compress the camera output and will have to send that stream over RTMP protocol to the Wowza server. At the receiving and, there should be a player which can decode, decompress that stream comes from the Wowza to the device like iPhone (a user who wants to see live stream).
My question is, if encoding is done through particular iOS SDK, RTMP has a role as a Protocol, a player at receiving end has a role of decoding, then what is the role of Wowza ? What is its function that makes it very important in the live streaming process ?
I have been searching on the function of a Media Streaming server since 3 days, but I could not understand the exact function of Media Streaming server like a Wowza.
I am desperate to the answer..
Any explanation will be appriciated, thanks in Advance !!!
I actually did a year-long project involving media streaming on iOS and I used Wowza. The role of Wowza is to function as a media server that can receive the video that is broadcast from an iOS device over the RTMP protocol. With Wowza, you have options to send http parameters that instruct the server to begin or stop recording the live video that is being streamed. You also have the option of embedding video players in websites for live view.
I'm trying to receive a live RTP audio stream in my iPhone but I don't know how to start. I'm seeking some samples but I can't find them anywhere.
I have a Windows desktop app which captures audio from the selected audio interface and streams it as ยต-law or a-law. This app works as an audio server that serves any incoming connection with that streaming. I have to say that I've developed an Android app that receives that stream and it works, so I want to replicate this functionality on iOS. In Android we have "android.net.rtp" package to manage this and transmit or receive data streams over the network.
Is there any kind of equivalent package for iOS to implement this? Could you give me any kind of reference / sample to do this, or just tell me where to start?
You can see this libraryHTTPLiveStreaming, But his protocol maybe is not standard one, You can check my fork aelam/HTTPLiveStreaming-1, I'm still working on it, it can be played by ffplay. You can try
check the file rtp.c in ffmpeg, I think it will help out
I have downloaded a library from this links its working fine for live streaming with in local network. I am not able to customize this library to communicate with wowza server. Please guide me if anyone knows.
Or else suggest me some other open source ios client library(Encoding foramt should be either H.264 or MPEG 2 or 4) to communicate with wowza server.
I recommend you to install wowza locally on your host, turn it on the max debug level and try to establish the session with you client. Then, in the log, you will see what is going on. As per my experience, wowza standard setup behaves in a pretty expectable way, understands h264 + aac sound. I implemented rtsp client for android, can send you negotiating logs, etc. You, on the other side, could also grab the log on how session is established to check if commands order is ok, all is sane and what the response is.
There is obviously a way to do this because so many applications are already doing it - NetCamViewer and iCamviewer to name just one.
I have searched and searched, but I'm not finding anything of value that gives a hint as to how this is done. I'm reaching out hoping that someone will give me a clue.
I'm trying to connect to an video security camera (Y-CAM), which supports the RTSP protocol, and display the video from my iPhone/iPad application. The camera has an IP address and I can view the video from a web browser and from Quicktime running on my Mac. The problem is that RSTP is not supported on iOS so even trying to connect using Safari on an iPad doesn't work.
I've read that some are trying to use Live5555, but I haven't seen an article that describes if it has been done successfully and how.
An alternative is to capture the RTSP stream on a server, convert it to an HTTP Live stream and then connect to the HTTP Live stream from iOS. Unfortunately, this hasn't proved as easy as it sounds.
I'd prefer to go directly to the camera like other applications I've seen do. the RTSP to Live is a fall back if I have to.
Any hints are greatly appreciated. Thanks!
This is wrong :) or not necessary (An alternative is to capture the RTSP stream on a server, convert it to an HTTP Live stream and then connect to the HTTP Live stream from iOS. Unfortunately, this hasn't proved as easy as it sounds.)
You should use ffmpeg library, as this library can connect any streaming server (supporting rtsp, mms, tcp, udp ,rtmp ...) and then draw pictures to the screen.. (for drawing you can use opengles or uiimage also works)
First of all, use avformat_open_input to connect to your ip address
then use avcodec_find_decoder & avcodec_open2 to find codecs and to open them (you should call them for both audio & video)
Then, in a while loop read packets from server by using av_read_frame method
When you get frame, if it is audio then sent it to AudioUnit or AudioQueue,
if it is video, then convert it from yuv to rgb format by using sws_scale method and draw the picture to the screen.
That's all.
look at this wrapper also (http://www.videostreamsdk.com), it's written on ffmpeg library and supports iOS
You really need to search stack overflow before posting , this question has been asked many times. Yes live 555 sort of works and some of us have gotten it to work..
There are other players too, including ours http://www.streammore.tv/
You can find an open source FFMepg Decoder for iOS (and somes samples) on GitHub : https://github.com/mooncatventures-group
Sample use of this library : http://sol3.typepad.com/exotic_particles/
There are two general technology to display RTSP video on iOS Safari:
RTSP / HLS (H.264+AAC)
RTSP / Websocket (H.264+AAC ==> MPEG+G.711 or H.264+?)
For HLS you can consider Wowza server.
For Websocket playback in iOS Safari you can use WCS4 server.
Main idea for websocket playback is direct HTML5 rendering to HTML page Canvas element and audio context. In the case of MPEG playback video decoding will be done on iOS Safari side using plain JavaScript.
Another option - install a WebRTC plugin with getUserMedia support and play this stream via WebRTC. Anyway you will need a server side RTSP-WebRTC transcoder in such case.
I'm trying to play a live stream that is being sent out by a Wowza server, we are using RTMP to handle the streams. We have an equivalent for that works on android and the way they do it is by connecting to the server via the url and 2 parameters to identify the actual stream to play and if you are allowed to see the live video. After the connection is attempted, the server does a call back sending an integer for a check to see if the user is logged in. Once the check has passed, the video is played.
I have no idea how to handle the call back or how to properly set up the connection so that it takes both parameters and the url.
One big issue is that the Wowza server was created by a third party that we are no longer in contact with, so i have no idea on how the actual server is set up.
Any suggestions would be greatly appreciated
I recommend a few steps to start with:
Determine how the Android app actually works. Is the the server you speak of to which it sends the two parameters the Wowza server? If so, it is probably a custom plugin.
Get access to the server, so that you can configure it for iOS streaming.
You'll also need to check out some documentation, http://www.wowza.com/forums/content.php?3-quick-start-guide, http://www.wowza.com/forums/content.php?217#cupertinostreaming
Once you have a better understanding of the problem, the Wowza folks are very helpful at http://www.wowza.com/forums.
Good luck!
there is no need to android apps etc. Wowza is supporting the output which can be played # ios, because of the ios cant play flash, then it cannot played rtmp or rtsp . However Ios can play the stream which is like http: // myWowzaServer/myApplication/myStream/playlist.m3u8 ...
